Embodiment 1

[0041] Design two circular grooves along the outer periphery of the inner tongue infusion tube of the pen. The nib ball of the hoop-type fountain pen head is fixed at the liquid inlet end of the water supply pipe inside the liquid outlet end. The opening of the side wall of the arc-shaped groove faces the liquid guide groove on the inner wall of the round hoop type pen tip. Select two rabbit hair fiber needles and place them in the two grooves of the inner tongue infusion tube of the pen respectively, and the distance between the head of the fiber hair needle and the head of the round hoop pen is 0.8mm. Inject a certain concentration of paint into the micro-liquid supply instrument, and draw an ultra-fine ultra-thin film with a width of 15.84 μm and a thickness of Figure 8 .

Embodiment 2

[0043]Design two circular grooves along the outer circumference of the inner tongue infusion tube of the pen. The nib ball of the hoop-type fountain pen head is fixed at the liquid inlet end of the water supply pipe inside the liquid outlet end. The opening of the side wall of the arc-shaped groove faces the liquid guide groove on the inner wall of the round hoop type pen tip. Select two stone badger hair needles and place them in the two grooves of the inner tongue infusion tube of the pen respectively. The head of the fiber hair needle is 1mm away from the head of the round hoop pen. A certain concentration of paint was injected into the micro-liquid supply instrument. Under the condition that the liquid supply rate was 1 μL / min, the tips of the two stone badger hair needles were in contact with the substrate, and the angle was 30°, the ultra-thin coating with a width of 35.45 μm and a thickness of Figure 9 .

Embodiment 3

[0045] Design two circular grooves along the outer circumference of the inner tongue infusion tube of the pen. The nib ball of the hoop-type fountain pen head is fixed at the liquid inlet end of the water supply pipe inside the liquid outlet end. The opening of the side wall of the arc-shaped groove faces the liquid guide groove on the inner wall of the round hoop type pen tip. Select two polymer fiber hair needles and place them in the two grooves of the inner tongue infusion tube of the pen respectively, and the distance between the head of the fiber hair needle and the head of the round hoop pen is 1.2mm. A certain concentration of paint is injected into the micro-liquid liquid supply instrument. Under the condition that the liquid supply speed is 1 μL / min, the tips of the two polymer hairs are in contact with the substrate, and the angle is 90°, a superplastic with a width of 49.02 μm and a thickness of Figure 10 .

Abstract

Provided is a pen type liquid guide infiltrating device, comprising a water supply tube (1). The device further comprises a pen tongue feed infusion tube (2), a circular hoop type pen head (3) and a fiber hair pin (4). The pen tongue feed infusion tube (2) is provided with two arc-shaped grooves (21) arranged along an outer circumference. The fiber hair pin (4) is fixed in the arc-shaped groove (21) of a liquid outlet end of the pen tongue feed infusion tube (2). The pen tongue feed infusion tube (2) passes through the circular hoop type pen head (3), and a side wall of the arc-shaped groove (21) is open toward a liquid guiding groove (31) of an inner wall of the circular hoop type pen head (3). The pen type liquid infiltration device effectively solves the problem of micro-liquid infiltration in a micro-liquid supply system.

Description

technical field [0001] The invention relates to the field of trace liquid infiltration devices, in particular to a pen-type liquid guide and infiltration device. Background technique [0002] Under normal circumstances, pens cannot draw lines on the surface of flat glass or silicon wafers, and even if they do, they will be drawn intermittently and irregularly. [0003] The distance between the inner tongue of the existing pen and the inner ring of the hoop type pen is on the order of microns, and its size directly affects that most of the trace liquids are gathered in the two grooves. [0004] The gap between the inner tongue of an ordinary pen and the metal ring of the nib is just a tubular gap with a bevel (the thickness is generally 500-800 μm). Under the action of capillary function, the liquid will be dispersed to all parts of the metal inner ring. The head of the metal nib has a slender slit about 300-500 μm wide to connect with the ball head of the nib (the ball hea...
